Definitions

  • the present invention relates to a particularly original cross-country ski boot because of the improvements which it benefits.
  • Cross-country skiing or Nordic skiing whether used as a means of utility travel or as a leisure and competition activity, allows you to move only at low speed on snow-covered flat or slightly hilly surfaces.
  • the boot is simply joined to the ski by the front of the sole and the skier must be able to walk while accelerating more or less the pace, but it is practically impossible for him to evolve by turning tight.
  • the cross-country ski boot has a relatively rigid sole on which is mounted a conventional upper whose tightening on the foot is generally ensured by lacing.
  • the rigidity of the sole is obtained by various means so that it can pivot at the end of the foot relative to the ski, bend in line with the metatarsus to allow the foot to unwind and in spite of this do not deform in torsion; it is indeed important that the actions of the foot on the sole can be transmitted to the ski by the latter without parasitic torsional deformations in particular disturbing the movement and causing the skier to lose in the effects obtained the precision and the purity of the movement such that it was ordered.
  • the present invention aims to remedy this drawback by perfecting the cross-country ski boot so that it blocks the foot in a vertical plane passing the longitudinal axis of the ski, while allowing the folding of this foot at the metatarsus ; thus, the ankle is neutralized for all lateral movements and the foot made integral with the lower leg in the abovementioned vertical plane, while participating, by firm support in torsion, in the anteroposterior metatarsal pivotings.
  • the ski boot comprises a shell made of rigid plastic material which can be dismounted on a walking shoe made of relatively thick flexible material for comfort and shoe size compensation; in the flexion zone to the right of the metatarsus, the upper part of the shell is fully perforated until substantially the outsole and the liner which is in closed pore foam, resistant to wear and more or less densified according to the place, has a thickened and compressible part which envelops the top of the foot and which has, opposite the metatarsal openwork of the shell, transverse grooves promoting anteroposterior flexion.
  • the outsole of the shell has, opposite the metatarsal perforation, transverse grooves also promoting anteroposterior flexion.
  • Such a shoe is particularly effective and efficient.
  • the removable liner housed in the rigid shell is not only intended to ensure the comfort and tightness of the wearing of the shell; in reality, this bootie is also designed, on the one hand, as a walking shoe and, on the other hand, as a shoe size compensator.
  • the cross-country ski boot of the invention comprises a shell 1 in which a boot 2 is inserted.
  • the shell 1 is manufactured by injection of a thermoplastic material having the required rigidity and resistant to bending at low temperature.
  • This shell is preferably constituted by elastomers of polyesters such as those sold under the name of Hytrel by du Pont de Nemours or of Arnitel by Akzo and prepared in the quality 55 shore D; it can also be constituted by a thermoplastic polyurethane from Bayer for example, by a polyamide such as that marketed under the name Zytel by du Pont de Nemours, by a polyester-polyamide copolymer, such as that marketed under the name Pebax by Ato-chimie.
  • the liner is made from flexible foaming products of the polyurethane family, preferably on a polyether base which better resist hydrolysis; but a polyester base may also be suitable.
  • the foam must be closed cell, so that the liner is waterproof and weatherproof: humidity, melt water, snow, ice ...
  • This foam must also be resistant to wear so that the liner can be used independently of the hull when driving a vehicle, walking on the ground to the track etc ...; said foam must also be relatively flexible in order to be deformable and compressible, in particular during the above-mentioned flexions of the foot; finally, it must be more or less densifiable by the use of conventional techniques so that certain parts (at the location of the sole for example) are relatively thin and compact while other parts (at the location of the metatarsus and of the instep) are relatively thick and compressible.
  • the shell 1 Since the shell 1 is molded in one piece, it monolithically includes a wear sole 3 and a rod 4. This rod has at its front end a toe 5 whose thickness is relatively reduced compared to to that of the outsole 5 which on the other hand is substantially uniform.
  • the toe 5 is made integral with a lug 6 intended for the flexing or articulated fixing of the boot on the ski, by means of a thinned tongue 7 extending the sole 3.
  • the rod 1 also has at its rear end a part 8 forming a buttress and quarters.
  • This rising part 8 is relatively low and has clearance notches 9 facing these ankles. These notches delimit at the instep side ears 10 and 11 which do not meet completely and are separated by a slot 12 across which is disposed a clamp 13 which connects said ears.
  • the ears 10 and 11 are also separated from the end 5 by a perforation 14 which extends to the outsole 3.
  • the shell 1 is relatively rigid but can however very easily bend at the 'location of the perforation 14 that is to say at the level of the metatarsus.
  • transverse grooves 15 can be formed recessed in the underside of the outsole 3 opposite the aforementioned cutout 14.
  • the liner 2 also came from molding but foaming with variable densification.
  • the liner is therefore monolithic and has a outsole 16 secured to a rod 17.
  • the outsole 16 has a substantially constant and relatively small thickness.
  • the rear part 18 of the rod which corresponds to the buttress and to the quarters of the shell as regards their upper cutouts, has a thickness which is also substantially constant but slightly greater.
  • the sole 16 and the rear part 18 of the upper are therefore relatively thin and compact.
  • the end 19 of the upper 17 of the liner is relatively thick and compressible. It is the same also for the part 20 of the rod which envelops the top of the foot and consequently fills the slot 12 and the perforation 14 of the shell.
  • This part 20 is thicker to the right of the perforation 14, that is to say of the metatarsus, than to the right of the ears 10, 11 and the tip 5, that is to say respectively of the instep and toes, zones in which the thickness of the part 20 is progressively decreasing as it moves away from the cutting 14.
  • part 20 of the liner protects the foot against external agents and against any bruising due to the hardness of the shell; in particular, by blocking the strap 33, the ears 10 and 11 of the shell are tightened on the liner and the upper 19 of this liner is compressed on the instep; this ensures perfect attachment of the shoe with the foot.
  • transverse grooves 21 are formed in the hollow in said part 20 in line with the cut-out 14; so the metatarsal flexion of the foot at through the liner is it greatly facilitated by the compressibility of the veil 22 which remains in the part 20 and the bringing together of the ribs 23 separating the grooves 21.
  • the whistle 24 is glued to the top of the outsole 3 of the shell 1. But it is obvious that the same whistle may have come from molding with the outsole 16 of the boot 2, a reinforcement of this whistle may possibly be provided.
  • the shell 1 and the liner 2 must remain integral with each other when they put on a foot and are tightened on it by the strap 13 and this not only during a walk in the absence of skis, but also when skiing.
  • the rear part 18 of the liner 2 is convex and cooperates by interlocking for its retention with the rear part 8 also convex and of complementary shape to the shell 1.
  • the neck 25 of the boot 2 which slightly overcomes the notches 9 is provided with a flexible lining 26 protecting the lower legs; this lining 26 is sewn on the neck and can possibly be extended by a kind of chimney fitting onto the socks.
